  • Tissue transglutaminase IgA antibodies

    This is the gold-standard, NHS-approved blood test for coeliac disease. We measure this in all cases.

  • Total IgA antibodies

    If your tissue transglutaminase IgA level is low, we'll go on and test your total IgA antibody level to make sure you produce this type of antibody.

  • Deamidated gliadin peptide IgG antibodies

    If you're found to be IgA deficient, we'll go on and test your deamidated gliadin peptide IgG antibody levels which can indicate coeliac disease.

  • Endomysial IgA antibodies

    If your tissue transglutaminase level is high, we'll go on and test your endomysial antibody levels to confirm that coeliac disease is highly likely.
